The American Express Centurion Black Gold Card is the black gold (highest) level version of the "Centurion Series Debit Card" launched by American Express in the UK in 1999[1]. Because the main color of the card surface is black, it is also called "black card". The Centurion Black Gold Card is recognized as the "King of Cards" in the world. This card is positioned at the top group and has no limit limit (the Centurion Black Gold Card in China is a cooperatively issued credit card, so there is a limit limit, and the credit limit is 2 to 10 million). Most of the cardholders are political figures, billionaires and celebrities from various countries and are invited by American Express. Card applications are not accepted. Cardholders can enjoy the world's top member-exclusive benefits, rights and services.
